SegLoc: Learning Segmentation-Based Representations for Privacy-Preserving Visual Localization

no code implementations CVPR 2023 Maxime Pietrantoni, Martin Humenberger, Torsten Sattler, Gabriela Csurka

Inspired by properties of semantic segmentation, in this paper we investigate how to leverage robust image segmentation in the context of privacy-preserving visual localization.

On the Limits of Pseudo Ground Truth in Visual Camera Re-localisation

1 code implementation ICCV 2021 Eric Brachmann, Martin Humenberger, Carsten Rother, Torsten Sattler

This begs the question whether the choice of the reference algorithm favours a certain family of re-localisation methods.

Robust Automatic Monocular Vehicle Speed Estimation for Traffic Surveillance

no code implementations ICCV 2021 Jerome Revaud, Martin Humenberger

Experimental results conducted on three diverse benchmarks demonstrate excellent speed estimation accuracy that could enable the wide use of CCTV cameras for traffic analysis, even in challenging conditions where state-of-the-art methods completely fail.

Robust Image Retrieval-based Visual Localization using Kapture

2 code implementations27 Jul 2020 Martin Humenberger, Yohann Cabon, Nicolas Guerin, Julien Morat, Vincent Leroy, Jérôme Revaud, Philippe Rerole, Noé Pion, Cesar De Souza, Gabriela Csurka

To demonstrate this, we present a versatile pipeline for visual localization that facilitates the use of different local and global features, 3D data (e. g. depth maps), non-vision sensor data (e. g. IMU, GPS, WiFi), and various processing algorithms.

Virtual KITTI 2

no code implementations29 Jan 2020 Yohann Cabon, Naila Murray, Martin Humenberger

This paper introduces an updated version of the well-known Virtual KITTI dataset which consists of 5 sequence clones from the KITTI tracking benchmark.

R2D2: Repeatable and Reliable Detector and Descriptor

1 code implementation14 Jun 2019 Jerome Revaud, Philippe Weinzaepfel, César De Souza, Noe Pion, Gabriela Csurka, Yohann Cabon, Martin Humenberger

In this work, we argue that salient regions are not necessarily discriminative, and therefore can harm the performance of the description.

From handcrafted to deep local features

1 code implementation26 Jul 2018 Gabriela Csurka, Christopher R. Dance, Martin Humenberger

This paper presents an overview of the evolution of local features from handcrafted to deep-learning-based methods, followed by a discussion of several benchmarks and papers evaluating such local features.
